A powerful lubricant, cleaner, and preservative aggressively formulated for use in firearms that run HARD. Weapon Shield™ cleans out carbon fouling, removes lead deposits, lubricates, and guards against extreme pressure and wear. And it's great at fighting corrosion, too. Its Advanced Boundary Film (ABF) technology reduces that coefficient of friction between the bullet and bore surface, improving the ballistic movement of the bullet to help promote more consistent groups and fewer flyers. Weapon Shield Grease for maximum lubricating effectiveness or for fast-moving parts where oil just "slings off". Weapon Shield Solvent effectively breaks up carbon fouling and helps remove lead residue from the bore without using toxic volatile chemicals. Maintenance Kit is a complete suite of products to clean, lubricate, and protect your firearms. Contains a ¼ fl. oz. needle oiler AND 4 fl. oz. bottle of Weapon Shield cleaner-lubricant-protectant, a 4 fl. oz. bottle of solvent, and a Weapon Shield Grease syringe.
